Why do laser rifles have recoil?

If the laser rifle is doing damage because of the force of the impact by the laser, the rifle would have an equal force pushing back on the one firing. If the laser rifle is doing damage because it is emitting a strong enough beam of light to burn the target, then there should be no recoil.

 

.... that sounds like a horribly inefficient way to produce light.

 

The most intense form of natural light is from a gamma burst. Obviously laser rifles have a gbm (gamma burst module). They're efficient because they're made in New Chinatown, Mars colony.

I think we can conclude that laser rifles would or would not have knockback in different circumstances

• if hitting with the kinetic force equal to a bullet = yes
• if hitting with nearly no force but dammaging through heat absorbtion/transfer = no/ not noticable to user.

of course the second would be more easily deflected and shielded against than the later to some degree

are we agreed?
If so shall I make a thread about chloroplasts/ fotosynthesis in animals in science fiction and its feasability as a modification of human or animal cells/organisms?

 

That just turns people into Moss Man.

 

you did not answer my question and jumped the gun on a thread I have not made yet.
